Injecting drugs can be a risky business in prohibitionist society. This is because hygiene is difficult, education is minimal, and fluctuations in quality can lead to accidental overdose. US opposition to needle-exchange programs at home and abroad has massively promoted the spread of HIV and hepatitis in users - and non-users - alike. Noxious tobacco-smoking aside, the Supreme Court of the United States has never been sympathetic to a drug-based lifestyle.... "
To be a confirmed drug addict is to be one of the walking dead....The teeth have rotted out, the appetite is lost, and the stomach and intestines don't function properly.
The gall bladder becomes inflamed; eyes and skin turn a bilious yellow; in some cases membranes of the nose turn a flaming red; the partition separating the nostrils is eaten away-breathing is difficult.
Oxygen in the blood decreases; bronchitis and tuberculosis develop.
Good traits of character disappear and bad ones emerge. Sex organs become affected.
Veins collapse and livid purplish scars remain. Boils and abscesses plague the skin; gnawing pain racks the body.
Nerves snap; vicious twitching develops. Imaginary and fantastic fears blight the mind and sometimes complete insanity results.
Often times, too, death comes-much too early in life....Such is the torment of being a drug addict; such is the plague of being one of the walking dead..." (1962)
Redefining Addiction Abstract: The Need to Redefine Addiction, R.G. Newman MD, M.P.H.
Newman examines the debate that surrounds how narcotic addiction should be defined. He argues that the traditional definition of narcotic addiction found in most medical textbooks, emphasizing physical dependency and tolerance associated with the patient’s current drug use, does not present an accurate or meaningful picture of the disorder. He suggests that any definition must account for the conflicting evidence related to the ability to maintain abstinence following repeated exposure to narcotics.
The medical literature is consistent in reporting a high rate of recidivism among those with opiate addictions following completion of even the most respected treatment programs. The greatest challenge that physicians (and patients) face is not achieving abstinence, but maintaining it. And yet, other studies over the last 25 years have demonstrated convincingly that many individuals that use narcotic drugs, even when the use is over long periods of time and at very high dosage and frequency, experience little if any difficulty both in achieving and maintaining abstinence.
Based upon his review of these conflicting findings Newman concludes that the widespread belief in the inevitability and irreversibility of addiction is based upon the limited experience of clinicians who treat a self-selected subgroup of users.
Dr. Newman ends his discussion by arguing that a definition of addiction, to be useful, must take into account the seemingly conflicting results that have been reported. He suggests that narcotic addiction be defined as an atypical response to exposure to opiates that is characterized by progressive by increasing consumption of the drug and a persistent disposition to relapse even after abstinence has been achieved and acute physical dependence has been reversed.

The Natural History of Opiate Dependence Abstract – Effective Medical Treatment of Opiate Addiction, National Institute of Health Consensus Statement 1997
Scientific evidence reviewed for the NIH report indicates that opiate dependence stems from a physiological medical disorder in the human brain that causes the addicted individual to crave and continue to use the substance despite the risk of physical or psychological harm. There is consistent evidence that medical treatment can be utilized to effectively manage this disorder and that treatment can provide substantial positive benefits to the addicted patient and society.
Investigators that have examined the biological, psychological and social factors that contribute to opiate abuse argue that most individuals that become dependent on opiates begin their cycle of addictive behavior early, generally in their twenties, and continue to use illicit drugs intermittently throughout their lifetime. They argue that repeated exposure to drugs such as opiates causes substance use to increase despite the adverse effects and harmful consequences that the individual may experience. The majority of individuals that become addicted to opiates develop a physiological dependence that gradually escalates as the body concomitantly builds up tolerance to the physical effects of the drug.
Once a pattern of physical dependence is firmly established the addicted patient enters repeated cycles of drug cessation and relapse that can continue throughout his or her lifespan. This pattern of dependence on opiates leads to what the experts call an addiction career that is usually accompanied by decades of legal problems and incarceration in public correctional facilities.
The Neurobiology, Pathology and Genetic Risk Factors Associated with Opioid Addiction and Dependence Abstract – Effective Medical Treatment of Opiate Addiction, National Institute of Health Consensus Statement 1997
Decades of clinical research on the neurobiology and pathology of opiate dependence have revealed that individual vulnerability to drug abuse is partially inherited and the pattern and degree of severity of this disorder are strongly influenced by environmental factors.
This conclusion is supported by evidence gathered in government-funded family, twin, and adoption studies that indicate that the children of opiate dependent parents have a higher predisposition and susceptibility to abuse and dependence after their initial use of opioids compared with children whose parents do not use drugs.
Neurobiological studies suggest that there are a number of opioid receptor pathways in the human cerebral cortex that play an important role in the development of drug dependence and the intensity of symptoms of physical withdrawal experienced by opiate addicted patients.
Definition of Opioid Dependence as a Medical Disorder Abstract – Effective Medical Treatment of Opiate Addiction, National Institute of Health Consensus Statement 1997
The Consensus panel at the National Institutes of Health defines opioid dependence as a cluster of cognitive, behavioral, and physiological symptoms in which an individual continues to use opiates despite significant physiological and psychological harm caused by the ingestion of the drugs.
The condition is characterized by the patient’s repeated self-administration of an opiate drug over an extended period of time resulting in the development of opioid tolerance, compulsive drug taking behavior, and withdrawal symptoms upon cessation of use. Patients may develop a dependence on opioids with or without symptoms of physiological tolerance and withdrawal; these patients usually have a long history of opioid self-administration either through intravenous drug injection, intranasal ingestion or smoking
Health care providers in the United States agree that although the factors that contribute to opiate dependency are poorly understood, one thing is certain: once physical dependence on opiates develops, it can constitute a medical disorder that requires treatment intervention. Methadone maintenance treatment in conjunction with medical attention and psychiatric counseling can do a great deal to alter the course of the natural history of opiate dependence and help prolong periods of abstinence from illicit drug use in addicted patients.
